Abstract

Radiology is a medical science that focuses on imaging technology. with results in the form of images /images for. to establish a diagnosis by looking at parts of the human body using X-rays so as to be able to provide professional examination services. The results of research that have been conducted at Aulia Hospital regarding the selection of CT scanogram settings for head scans with clinical chepalgia using the upper limit of the vertex and the lower limit of the mandibular because the location of the abnormality in the patient is not known whether in the nerve or sinus, if the scanogram is made to the lower limit of the petrous pars it still cuts the cerebrum so that the sinuses are still cut. whereas in the Radiology installation of Reksodiwiryo Padang Hospital uses a scanogram of the lower limit of the cranii base and the upper limit of the vertex to minimize the radiation received by the patient. Based on this, socialization activities through a pocket book of research results were carried out at Reksodiwiryo Padang Hospital on August 10, 2023 starting at 08.00 - 12.00 WIB, with participants being radiographers in the Radiology installation of Reksodiwiryo Padang Hospital.  The methods used were lecture, discussion and question and answer. With communication that is two way traffic, there is a direct reciprocal relationship between the speaker and the participants or vice versa. This method applied can focus the attention of participants in training to develop thinking power and skills to express opinions in the form of exchanging information in solving a problem. The results of the socialization of the pocket book of research results on the effectiveness of CT scan management of the head with clinical chepalgia were 98% able to increase radiographers' knowledge in the selection of scanogram settings on CT scans of the head with chepalgia able to produce images that enforce dignosa

Abstract

The quality of radiographic images is the accuracy of the patient's anatomical representation on the radiographic image. To produce high-quality images, the most important characteristics of radiographic image quality are spatial resolution, contrast resolution, noise, and artifacts. An increase in tube current causes a decrease in noise value. In radiographic imaging, noise is influenced by several factors including the strength of the tube current. Basically the tube current chosen is at the highest mAs that the aircraft can achieve, so that the exposure time can be as short as possible, so as to prevent image blurring caused by movement. This study aims to analyze the influence of mAs varieties on noise on radiographic images. This research was carried out using an experimental study method at Siti Rahma Padang Hospital, on May 27, 2024. Using the phantom pelvis of Baiturrahmah University Padang to obtain the results of the description of five different variations of mAs: mAs 8, mAs 10, mAs 12, mAs 14, mAs 16, with a tube voltage of 70. The data was processed using SPSS using the ANOVA One Way test, in the form of a table. Producing a calculated F value of 4.673 which shows a significant relationship between the strength of the tube current and noise with ap value of 0.002 (< 0.05). This study concluded that there was a significant influence between the results of mAs variation on noise.

Abstract

Computed Tomography (CT) is an essential imaging modality for evaluating head trauma due to its ability to provide detailed cross-sectional images. Image quality, particularly the Contrast to Noise Ratio (CNR), plays an important role in diagnostic accuracy. This study aimed to determine the effect of reconstruction increment variations on CNR values in head trauma CT examinations and to identify the increment that provides the most optimal image quality. This research was a quantitative experimental study conducted at the Radiology Unit of RSUD Prof. Dr. M.A. Hanafiah, SM Batusangkar, in February 2025. The population consisted of all patients who underwent CT brain examinations with clinical head trauma during the study period, totaling 12 patients, of whom five patients were selected as samples using purposive sampling. Secondary image data were reconstructed using two increment variations, 0.7 mm and 1 mm, with identical scanning parameters. CNR values were calculated using Radiant Viewer by measuring regions of interest (ROI), and the data were analyzed using the Shapiro–Wilk normality test followed by the Independent Samples T-Test. The results showed that the mean CNR value for the 0.7 mm increment was 304.52, which was higher than the 1 mm increment with a mean CNR of 288.51. However, statistical analysis demonstrated no significant difference between the two increment variations (p = 0.155; p > 0.05). In conclusion, both reconstruction increments produce comparable image quality in head trauma CT examinations. Nevertheless, the 0.7 mm increment provides higher CNR values and may be considered more optimal for improving image clarity

Abstract

The anteroposterior (AP) projection of the Ossa Pedis examination technique in some hospitals typically uses a perpendicular 0° beam angle, while the theoretical approach uses a 10° cephalad beam angle. This study aims to compare variations in 0° and 10° cephalad beam angles and provide more informative anatomical information. The study used a quantitative experimental approach in the Radiology Laboratory of the Faculty of Vocational Studies, Baiturrahmah University, from June to August 2025. The study involved a population of 79 individuals and a sample size of 3 individuals. Data were collected through radiographic images and then assessed by 5 radiology specialists and 25 radiographers using a questionnaire with a 5-item Likert scale. Question 1 depicts the anatomy of the tarsal bones, Question 2 depicts the space between the metatarsals, Question 3 depicts the lower part of the metatarsals, Question 4 depicts the joint space between the medial cuneiform and the intermedial cuneiform, Question 5 depicts the joint space between the interphalangeal joint, metatarsophalangeal joint, and tarsometatarsal joint. Data processing using SPSS with the Wilcoxon test is presented in figures and tables. Based on the results, the 0° angle produced a lower average value of 17.64, while the 10° cephalad angle produced a more optimal image with a higher average value of 22.72. This image has the advantage of a more open joint space, a more defined metatarsal base, and clearer alignment of the foot bones due to reduced superposition. With a p-value of <0.005, it can be concluded that there are differences in the anatomical images in the anteroposterior (AP) projection pedis examination at 0° and 10° cephalad angles.
